				<p>If at least a tiny part of the image has not loaded for 1 second or a browser does not support progressive loading, a spinning progress indicator smoothly fades in. A delay is added to avoid blinking in case the image was cached or the user has a fast connection.</p>

				<h3>Zoom animation</h3>

			<p>The background can be set to any color and transparency level.</p>
			<p>The vertical margins between images can be controlled through an API.</p>
			<p>PhotoSwipe is treated as a modal dialog, so <code>aria</code> attributes are added, and the gallery gains focus when it is open.</p>

    <div class="section">
			<div class="row title-block">
			<h2>Problems solved by PhotoSwipe</h2>
			<p>Images are displayed at their highest possible size and are not limited by the width of the column or wrapper. Each image is isolated from the other content and fits the viewport vertically, so that the user can focus on it. If an image is larger than the viewport, it can be zoomed (which most galleries are unable to do).</p>
		</div>

		<div class="row">

			<h3>Detail is preserved in responsive images</h3>
			<p>Let’s say the viewport on a user’s phone is 500 pixels wide and your uncompressed image is 1200 pixels wide. You wouldn’t want to serve such a large image on mobile, so perhaps you’d resize it to 500 pixels. But if the image has important details and the user zooms it, it will look pixelated. With PhotoSwipe, when the user taps the small image (500 pixels), the large one will load (1200 pixels), thus preserving all of the detail.</p>

			<h3>Compared to an inline horizontal JavaScript gallery</h3>
			<p>PhotoSwipe will not slow the page from loading, because you can defer loading the gallery’s JavaScript file or even load it after the user has clicked the “Open gallery” button.</p>

			<h3>Compared to a list of images, one after another</h3>
			<p>PhotoSwipe saves users’ bandwidth because it doesn’t load all images at once &mdash; just nearby images according to the user’s direction of movement. Also, it occupies less space on the page, and you can directly link to individual images in a gallery.</p>

		</div>



		<div class="row">
			<h3>PhotoSwipe might not be a good idea if…</h3>
			<ul>  
				<li>… your images are small or low quality or if there would be no point in zooming or isolating them. Use a simple list of images or a horizontal scroller instead.</li>
				<li>… your images are very large and should never be scaled (for example tall infographics with text). Simply link to image file, or create separate HTML page just with image.</li>
				<li>… your captions are long or more important than the images themselves. Consider using a simple list of images, with captions below or beside them. And when the user clicks on an image for which a larger version is available, then you could open PhotoSwipe, without the caption, to draw attention to the image itself.</li>
				<li>… your website’s layout is not fluid. On a non-responsive website on a small screen, PhotoSwipe’s controls would look tiny because the page will be zoomed out. Consider using Magnific Popup instead.</li>

			<ul class="text-list">
				<li>desktop Chrome, Firefox, Safari, Opera and IE 8 and above</li>
				<li>Android 2.3.7+ (2.1 not tested yet): default browser, Chrome, Firefox (latest), Dolphin (latest)</li>
				<li>iOS 5+</li>
				<li>Windows Phone 7+: default browser (touch gestures are supported from 8+)</li>
				<li>BlackBerry OS 10+: default browser (older versions not tested yet)</li>
				<li>devices with multiple input methods (Surface, Chromebook Pixel, etc.)</li>
			</ul>
			<p>If you discover a problem on your device, please <a href="https://github.com/dimsemenov/PhotoSwipe/issues">open an issue on GitHub</a>, and provide as much detail as possible (OS name and version, browser name and version, screenshot or screencast, etc.).</p>
		</div>

		<div class="row">
			<h3>How PhotoSwipe determines whether a mouse is being used</h3>
			<p>If both touch and mouse input methods are detected, the script waits for two consecutive <code>mousemove</code> events to occur and only then applies the mouse-only features (for example left/right arrow buttons).</p>
	    </div>
		
		<div class="row">
	        <h3>How the zoom animation works for opening images</h3>
	        <ol>
				<li>Once a thumbnail is clicked, its large version instantly starts loading.</li>
				<li>Meanwhile, PhotoSwipe creates a fixed-positioned layer with the duplicated thumbnail image, background, buttons and caption. The background and controls are styled with <code>opacity: 0.001</code> (if it had <code>opacity: 0</code>, the paint would not occur in some browsers).</li>
				<li>A 50-millisecond timer starts. It is added to give the browser time to render the new layers (background, controls, image). Otherwise, the animation would start with a noticeable lag. TODO: change this delay depending on browser/os/device?</li>
				<li>Three CSS transitions start: one scales the image (<code>scale</code> and <code>translate</code> are animated), the second changes the opacity of the background, and the third changes the opacity of the controls.<br>By default, the transition lasts 333 milliseconds.<br>The background is a separate element, because animating <code>opacity</code> looks much smoother than animating an RGBa <code>background-color</code>.</li>
				<li>Once the transition is complete, the large image is added on top of the stretched thumbnail, whether or not it’s fully loaded.</li>
				<li>To make the swipe transition smooth, the two neighboring slides are readied at the sides of the viewport.</li>

			<h3>Are PhotoSwipe images crawlable by search engines?</h3>
			<p>PhotoSwipe does not force any HTML markup into the gallery &mdash; you have full control. Images will be crawlable if you'll have list of links to large images or the images themselves.</p>
